**问题**: 我该如何在 Elemetary OS Luna 上安装Oracle Java 7？


**回答**: 在 Elementary OS Luna 安装 Java 7 的步骤如下: 由于Elementary OS是基于Ubuntu，所以我们允许使用具有多种Java包的**WEPUD8 PPA**。


1. 打开终端。
2. 运行以下指令添加Java的PPA到你的软件仓:



```
$ sudo add-apt-repository ppa:webupd8team/java

You are about to add the following PPA to your system:
Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK6 / JDK7 / JDK8). There are no actual Java files in this PPA. More info: http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html
Debian installation instructions: http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html
More info: https://launchpad.net/~webupd8team/+archive/java
Press [ENTER] to continue or ctrl-c to cancel adding it

```
3. 按回车继续



```
gpg: keyring `/tmp/tmpB5WwDG/secring.gpg' created
gpg: keyring `/tmp/tmpB5WwDG/pubring.gpg' created
gpg: requesting key EEA14886 from hkp server keyserver.ubuntu.com
gpg: /tmp/tmpB5WwDG/trustdb.gpg: trustdb created
gpg: key EEA14886: public key "Launchpad VLC" imported
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
OK

```
4. 现在更新你的系统



```
$ sudo apt-get update

```
5. 运行以下命令安装Java 7:



```
$ sudo apt-get install oracle-java7-installer

[sudo] password for enock:

Do you want to continue [Y/n]?

```
6. 输入代表Yes的**Y**以及回车键继续安装。
7. 在安装过程中，你需要同意条款才能继续。选择**OK**。

10. 安装完成。你可以在终端上查看Java版本:



```
$ java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

```
